Fluidized bed steam reformed mineral waste form performance testing to support Hanford Supplemental Low Activity Waste Immobilization Technology Selection

Abstract

of TTT for performing the engineering scale FBSR studies on a nonradioactive Hanford Tank Blend waste and providing the FBSR bed and fines materials produced for the SRNL WFO studies supported by ART. This data was used for comparison to non-radioactive and radioactive studies performed at SRNL at the bench-scale for the same Hanford Tank Blend waste as detailed in this report. The authors would also like to thank TTT for their technical guidance and support during the execution of the radioactive work scope at SRNL. The authors would like to thank the following SRNL personnel: Holly Hall and all the regulatory support personnel including Bill Wilson, Kerri Crawford, and Amy Blunt for all the guidance that has helped SRNL perform these treatability studies in compliance with Resource Conservation & Recovery Act (RCRA) waste handling procedures.The SRNL researchers would like to thank Babb Attaway, who is manager of the SRNL Shielded Cell Operations (SCO) group, and the SCO technical team consisting of Carolyn Conley,

Radioactive Demonstration Of Mineralized Waste Forms Made From Hanford Low Activity Waste (Tank Farm Blend) By Fluidized Bed Steam Reformation (FBSR)

“…Contained Scanning Electron Microscopy (CSEM) will also be performed. This will be documented elsewhere [51,86] 15. Determine the effect of Al, Si, and nepheline saturated solutions on Re and Tc-99 release from the FBSR product.…”

“…Ultimately it was decided through review of past monolith testing [51] to pursue the lower waste loading 'centroid' in the G1 region of Figure 4-14 formulation involving clay.…”
